observerat

Observerat is a neologism used in discussions of observation and measurement to denote the locus or context of observation—the point, frame, or state of the observer during data collection. In its broad sense, observerat encompasses both the physical location of the observer and the interpretive stance that the observer brings to what is being observed. In philosophy of science and epistemology, it is used to highlight how observations are inseparable from the observer's perspective and how the report of data is indexed to that perspective.

Origin and usage: The term combines observer with at and does not have a single formal definition. It is not widely standardized and appears in a range of interdisciplinary writings and glossaries since the early 21st century, often as a convenient shorthand rather than an established technical term.

Applications: In physics and the philosophy of science, observerat is used to discuss how measurements depend on the observer's frame of reference and can influence interpretation. In experimental design and data provenance, observerat can refer to the metadata about who or what performed an observation, where, and under what conditions.

Relation to other concepts: It overlaps with the observer effect, the frame of reference, and data provenance; some scholars view it as redundant, while others see value in it as a compact descriptor for observer-centric data.
